Barnet teacher Colin Purkey publishes memoir of apartheid imprisonment

A retired physics teacher from Barnet has published a memoir recounting his imprisonment under South Africa’s apartheid regime. Colin Purkey, who taught at a further education college for over 20 years, was arrested in the 1980s for posting a letter on behalf of a leading anti-apartheid activist. His book, 'Time Served', was reviewed by the Barnet Post on 2 August 2026.

Purkey’s memoir is structured in three distinct sections, each covering a different period of his life. The first details his months in prison following his arrest. The second recounts his hospitalisation after being hit by a car as a teenager. The third section focuses on his involvement in the anti-apartheid movement during the 1980s and early 1990s, as the regime began to collapse.

The book blends personal narrative with historical events. Purkey describes security police raids on his home, where officers conducted searches and made threats about incriminating documents. He also reflects on the broader impact of his activism, including the strain on his relationships and the necessity of holding meetings in secret to avoid detection.

The Barnet Post’s review, written by David Floyd, notes that 'Time Served' offers a deeply personal take on a significant political period. Purkey’s account shifts between his immediate experiences and broader memories, such as his time at university, where he first encountered ideas that would later motivate his activism.

Floyd describes the memoir as difficult to categorise. While it recounts major historical events, it does so through Purkey’s individual perspective. The narrative is not always linear, with frequent detours into related memories. The second section, which covers his hospitalisation, even includes a discussion on the philosophy of consciousness, breaking from the book’s political themes.

Despite his own distressing experience, he understands the privileges that liberal white activists had in comparison to the black majority on the receiving end of the regime’s actions.

Purkey acknowledges the limitations of his perspective as a white activist. The Barnet Post highlights his self-awareness, noting that he recognises the relative privileges he held compared to the black majority who bore the brunt of apartheid’s oppression.

Who will read it

The Barnet Post suggests the memoir will appeal to readers interested in activism and the personal experiences of those who opposed apartheid. However, some may find the level of detail and the non-linear structure challenging. For students of South African history, the book is described as an invaluable primary source, offering firsthand insights into the final years of the apartheid regime.

What happens next

It is unclear whether Purkey plans further public events or discussions about his memoir. The Barnet Post’s review does not mention any upcoming book signings or talks. Residents interested in obtaining a copy can check local bookshops or online retailers for availability.
